We were in post-production, and I got a call from (Warner Bros. head) Peter Roth, who said, ‘I know you’re closing, but could you put Ezra in the crossover?’“.
I replied to him: “Yes, I’ve wrapped up filming, but if you tell me Ezra Miller has to be in the crossover, I can make it happen.” So I called Eric Wallace, the Flash showrunner, and Grant Gustin, because our only concern was that we wouldn’t done unless Grant 100% agreed, which he was“.
And he continued: “Grant was incredibly enthusiastic and agreed. And then we got on the phone with Ezra Miller and described the scene to him that I wrote and he was happy with it. And so we shot it. And much to our surprise, no one noticed that Ezra Miller was in Vancouver and no one on the crew leaked the news. So we were able to keep Ezra’s presence a surprise until the very end“.
